Upper Delaware, New York
West Branch Delaware Fishing Report: July 28, 2026
The West Branch is cold and fishable around Hale Eddy this morning, with midday sulphurs up top and streamers becoming a better backup if storm runoff adds stain.
- Status
- good
- Flow trend
- rising
- Best window
- Midday sulphurs near Deposit before heavier storms build
- Best methods
- dry flies, wet flies, nymphs, streamers
Quick Summary
The West Branch is still the best New York trout option in this morning set, but today is not a casual weather day. USGS showed 591 cfs, 2.93 feet, and 48.4 F at Hale Eddy during the 9 AM refresh, and current Delaware-system source context still points to a 500 cfs Cannonsville release. The river has bumped up slightly from yesterday and remains cold and fishable, especially from a boat or known soft-edge wade spots. Fish the midday sulphur and olive window near Deposit if storms hold off; if heavier rain adds color, streamers become a better backup than forcing delicate dry-fly fishing through runoff. Be ready to leave the river quickly if rain cells, thunder, or rising water develop.
Conditions Snapshot
| Field | Value |
|---|---|
| Status | Good, with a weather caution. Cold tailwater temperature and a steady release keep the West Branch fishable, but heavy rain and thunderstorms can change safety quickly |
| Flow | 591 cfs at Hale Eddy during the 9 AM USGS refresh |
| Gauge Height | 2.93 feet at Hale Eddy |
| Water Temp | 48.4 F at Hale Eddy |
| Clarity | Not reported by official gauges; local Delaware context points to fishable water, with algae still a problem on the upper West Branch |
| Trend | Slightly rising compared with yesterday morning at Hale Eddy |
| Best Window | Midday sulphurs near Deposit before heavier storms build; late day only if radar and river levels remain safe |
| Best Method | Dry flies and emergers during sulphur and olive activity; soft hackles or nymphs in cleaner lower-river seams if fish are not rising; streamers if storm runoff adds stain |
| Wadeability | Limited. The flow is workable in known spots, but boats remain easier, and storms make long crossings a poor choice |
Weather
For Hancock and Hale Eddy, the National Weather Service forecast calls for cloudy conditions, a high near 75 F, and showers and thunderstorms becoming likely to widespread from late morning through the afternoon. Some storms could produce heavy rain, with 1 to 2 inches possible today and another 1 to 2 inches possible tonight. Wind should be light to moderate from the southeast and south, but lightning, hard rain, and fast tributary bumps are the main concerns.
River Notes
The Hale Eddy gauge is only a little higher than Monday morning, so the morning river itself is still in a good summer tailwater range. The bigger decision is weather timing. Start close to an exit, keep an eye on the radar, and avoid committing to long floats or pushy crossings if thunderstorms are building upstream. The upper West Branch has the coldest water and the main sulphur opportunity, but local context continues to point to algae up top; dries, emergers, and short soft-hackle presentations are cleaner than dragging heavy nymph rigs through mats. If runoff adds stain later, a small to medium olive, black, or white streamer along softer banks and structure is worth carrying, but do not use streamer fishing as a reason to stay on the water through thunder or a fast rise.
Hatch Activity
Official gauges do not report hatches. Current Delaware-system reports and late-July tailwater timing support sulphurs, small olives, Isonychias, tan caddis, Light Cahills, spinners, and terrestrials. The upper West Branch sulphur window remains the main dry-fly play, with smaller flies and emergers important on flat water.
| Hatch | Size | Notes |
|---|---|---|
| Sulphur | 16-20 | Main upper-West Branch hatch; carry duns, emergers, cripples, and soft hackles |
| Blue Winged Olive | 16-24 | Small olives can mix with sulphurs, especially under clouds or during unsettled weather |
| Isonychia | 10-14 | Useful as a larger wet, nymph, or searching dry around riffles and broken edges |
| Tan Caddis | 16-20 | Pupa, soft hackles, and adults cover seams between mayfly pushes |
| Light Cahill | 14-16 | Pale evening or searching mayfly for broken water |
| Rusty and Sulphur Spinners | 16-24 | Carry for last light, but skip the spinner fall if thunder or hard rain is nearby |
| Ants and Beetles | 14-20 | Good bank-side backup during quiet periods between mayfly activity |
Recommended Flies
| Category | Fly | Size | Notes |
|---|---|---|---|
| Dry | Sulphur Sparkle Dun, Comparadun, or CDC Emerger | 16-20 | Primary match for upper West Branch risers |
| Dry | BWO Comparadun or CDC Dun | 16-24 | Use when fish key on smaller olives mixed into the hatch |
| Dry | Isonychia Parachute or Comparadun | 10-14 | Larger profile for riffle edges and dry-dropper searching |
| Dry | Elk Hair Caddis or X-Caddis | 16-20 | Small tan caddis option for riffles and seams |
| Dry | Light Cahill or White Wulff | 14-16 | Visible pale dry for evening broken water |
| Dry | Rusty Spinner or Sulphur Spinner | 16-24 | Keep ready for last light only if weather stays safe |
| Dry | Ant or Beetle | 14-20 | Bank-side option when surface activity pauses |
| Wet | Soft Hackle Sulphur or Soft Hackle Pheasant Tail | 14-18 | Swing through riffle tails during emergences |
| Nymph | Pheasant Tail, Frenchie, or Split-Back Mayfly | 14-18 | Use in cleaner lower-river seams and check for algae often |
| Nymph | Isonychia Nymph | 10-12 | Good larger subsurface choice near riffle edges |
| Streamer | Woolly Bugger, Sculpin, or Zonker | 4-8 | Carry for stained water after storms; fish edges and structure only while lightning and river levels remain safe |
Tactics
Start with observation and weather awareness. If sulphurs or olives are moving, fish one accurate dry or a dry with a small emerger dropper and lengthen the leader for slick water. If the surface is quiet, swing soft hackles through riffle tails or nymph the cleaner lower West Branch with a sparse rig. If heavy showers stain the river but flows remain safe, switch to a streamer on a short leash along banks, wood, and softer structure. Keep wading conservative near 600 cfs, stay off long crossings, and leave the water immediately if thunder is close or the river starts rising quickly from heavy rain.
